Will these bolt into my factory fog light holes without modifications?

Yes. These mount at the factory fog light mounting points with no drilling or cutting required. Install as a direct swap for OEM units.

Do I need to wire the DRL function separately, or does it integrate with my existing wiring?

Wiring configuration is not specified — test-fit and trace your OEM fog light harness before committing to final connections. You may need an adaptor or relay depending on your vehicle's factory electrical setup.

Can I return these if they don't fit or the color doesn't match my bumper in person?

Check our return policy on the order confirmation page. We recommend verifying fitment photos against your specific bumper trim before purchase if color matching is critical.
